Question

. He buys 2 used books and 1 new book for $26 . the new book costs $18 . each used book costs the same amount what price of each used book

Answer 1

Cost of new book= $18

Remaining amount after subtracting the cost of new book = $(26 - 18) = $ 8

Cost of 2 used books = $ 8
Cost of 1 used book = 8/2 = $ 4

Answer 2

(total price - price of 1 new book)÷number of used books

($26-$18)/2=4
